I use underquilts or pads. It depends. If I think I might have to sleep on the ground (or pretend to, anyway) I take pads and use them in the hammock when I can. Usually a NeoAir and a thin foam pad that I also use as a sit pad or to keep the NeoAir from sliding around. In the hammock the foam pad goes under my head/shoulders sideways.

www.jacksrbetter.com has some examples of underquilt - there are several other vendors that make very nice ones in various lengths.

I am saying that FOR ME I cannot sleep on the ground. I have tried and tried. I wake up and toss and turn and cannot sleep. I have spent many nights trying this year. I just completed four nights above 10k on the ground and probably slept maybe four hours a night.

If I have a hammock I am warmer, cleaner, and happier. I could have hammocked three of the four nights as there were sufficient pines in all but one spot.

There are many people who hammock because of physical issues and pick destinations based on whether they can hang the hammock because they CANNOT sleep on the ground. I don't have physical issues; I just don't sleep well on the ground and very much dislike hiking multi-day outings with so little sleep I can't function.

Does anyone go backpacking with a dog (small-mid), if yes, where does it sleep? Does it sleep under you if it is a mid to larger size dog, and with you inside the hammock like in this video? https://www.youtube.com/watch?v=tcZlq_O-hxY

I don't give out specific route information, my belief is that it takes away from the whole adventure spirit of a trip, if you need every inch planned out, you'll have to get that from someone else.

I have two dogs that I take with me. They both sleep on a pad under me. I have been using a hammock for 8 years in all kinds of weather. The coldest that I have used mine was 2 degrees in 35-40 mph winds and deep snow. Was cozy and warm. I camped that night with two guys that had just returned from Ely, MN where the used their hammocks down to -27 degrees. Both my dogs gave insulated vests that they sleep in as well.
